(PHP 4 >= 4.3.0)
ftp_nb_fget -- Retrieves a file from the FTP server and writes it to an open file (non-blocking)
說明
int ftp_nb_fget ( resource ftp_stream, resource handle, string remote_file, int mode [, int resumepos])
ftp_nb_fget() retrieves remote_file from the FTP server, and writes it to the given file pointer, handle. The transfer mode specified must be either FTP_ASCII or FTP_BINARY. The difference between this function and the ftp_fget() is that this function retrieves the file asynchronously, so your program can perform other operations while the file is being downloaded.
